Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific implementation mode is only used for describing and explaining the present invention, and is not intended to limit the utility model.
Fig. 1 is the flow chart of the control device for the refrigerator compartment lamp brightness that one embodiment of the utility model provides.Such as Fig. 1 institutes
Show, the control device of refrigerator compartment lamp brightness provided by the utility model may include：Lighting device 1, between the refrigerator
Room provides illumination；Switching device 2, the circuit for the lighting device 1 that is turned on or off；Photosensitive sensor 3, for acquiring
State the intensity of illumination of the environment residing for refrigerator；And control module 4, the control module 4 are used for：Receive the lighting device 1
The intensity of illumination of environment residing for be turned on or off state and the refrigerator of circuit；And the electricity in the lighting device 1
In the state that road is on, the intensity of illumination of the environment residing for the refrigerator controls the brightness of the lighting device 1.
That is, after the circuit of the lighting device 1 is connected in the switching device 2, the control module 4 can be according to the photosensitive biography
The different illumination intensity for the environment residing for the refrigerator that sensor 3 is acquired, come control the lighting device 1 export it is different bright
Degree, the lighting device 1, which generates instantaneous large-current, when can prevent night from opening the refrigerator makes the brightness of the refrigerator inside
In dazzling, to effectively increase the service life of lighting device, the power consumption of refrigerator is reduced.
LED light lamp or incandescent lamp can be used in the lighting device 1, since LED light lamp is compared with incandescent lamp,
More energy efficient environmental protection, the service life is longer, therefore the utility model uses LED light lamp 5.The switching device 2 can be Men Kaijian
Slowdown monitoring circuit or mechanical switch, automatic shutter can be realized by opening or closing the door of the refrigerator by opening detection circuit due to door
The function of the lighting device 1, therefore the utility model uses and opens detection circuit 6 with door, which opens detection circuit for detecting
The door of the refrigerator opens or closes, and controls the lighting device that is turned on or off according to opening or closing for this
Circuit.Photosensitive sensor 3 can be the photoelectric tube, photomultiplier, photo resistance and phototriode etc..The control mould

The duty ratio for stating pulse width modulation wave is added to the reduction of linear function relationship with the intensity of illumination.Not according to above-mentioned three kinds
Same intensity of illumination range, the pulse width modulation control circuit 9 are used to export the pulse width tune of different duty
Wave processed, since the brightness of the LED light lamp 5 is directly proportional to the duty ratio of the pulse width modulation wave (such as Fig. 3 institutes
Show), therefore the intensity of illumination of environment of the controller 7 residing for the refrigerator controls the brightness of the LED light lamp 5
Also following three kinds of situations are shown as：When the intensity of illumination is less than first threshold, the controller 7 controls the light-emitting diodes
The brightness of spot 5 is reduced to constant luminance, that is to say, that opens ice in the case that user is at night or extremely dark at this time
The brightness of the LED light lamp 5 is reduced to the brightness for comparing mitigation by case, dazzling dazzling to prevent；When the illumination
When intensity is more than second threshold, such as user, when opening refrigerator daytime, the controller 7 directly closes the light-emitting diodes
Spot, because the intensity of illumination of environment is stronger, therefore the even LED light lamp 5 does not shine when opening refrigerator doors, Yong Huye
Refrigerator can be used normally, to greatly reduce the power consumption of the refrigerator；And when the intensity of illumination is more than the first threshold
When being worth and being less than second threshold, the controller 7 controls the brightness of the LED light lamp 5 with the increase of the intensity of illumination
And it reducing, it is preferable that the brightness of the LED light lamp 5 is added to the reduction of linear function relationship with the intensity of illumination,
That is, user opens refrigerator in the case of different illumination intensity, the brightness of the LED light lamp 5 can obviously not
Together, requirement of the user to refrigerator compartment brightness can not only have been met in this way, but also can be with save electricity.The present embodiment passes through described photosensitive
Sensor 3 and the pulse width modulation control circuit 9 control the brightness of the LED light lamp 5, i.e., according to different
Intensity of illumination exports different pulse width modulation wave duty ratios, different by different pulse width modulation wave Duty ratio controls
LED light lamp 5 brightness, avoid when opening the door of the refrigerator, the circuit of the LED light lamp generates wink
Between high current certain impact is caused to the LED light lamp, to effectively increase LED light lamp use the longevity
Life reduces refrigerator power consumption.
In conclusion the utility model acquires the intensity of illumination of the environment residing for the refrigerator, root by photosensitive sensor
The brightness that lighting device is controlled according to different intensity of illumination control modules, illumination dress when being effectively prevented the night unlatching refrigerator
Setting generation instantaneous large-current keeps the brightness of the refrigerator inside excessively dazzling, to effectively increase the use longevity of lighting device
Life, reduces the power consumption of refrigerator.
